Abstract

A method is described for calculating the values of day/night noise level (Ldn), at a point, due to aircraft operations from an airport. Two levels of sophistication are detailed; (1) at the basic level, such factors as type of takeoff and landing procedure are considered, but range and non-standard glide slopes are excluded, (2) the more detailed method takes account of the latter parameters. The procedure used is to locate the position of the point in question, relative to the runway and aircraft flight track. A series of charts give Ldn values for different types of aircraft in terms of the distance parameters. Adjustments are made to the single event noise levels to account for frequency of operations and the adjusted levels are added logarithmically to represent all of the classes of aircraft using the airport.
